The High Court has ruled that a District Court judge was wrong in law to find that Tim O’Connor had been unlawfully detained during an investigation into an alleged drink-driving offence and to dismiss the charge on that basis.
Mr Justice Quirke delivered the judgment on 14 December 2005 in a case stated by Judge James Paul McDonnell of Tallaght District Court. The Director of Public Prosecutions had asked the High Court to decide whether the District Court was correct to find that Mr O’Connor’s detention at Terenure Garda Station included an unjustified seven-minute period.
The alleged offence related to driving on the Tallaght bypass on 29 September 2001. The charge was that Mr O’Connor drove with an alcohol concentration in his breath above the statutory limit. He denied the offence. The High Court judgment records that he provided two breath specimens after Gardaí applied the statutory procedure; the machine recorded 127 microgrammes of alcohol per 100 millilitres of breath.
The District Court judge found that Mr O’Connor had been detained at the station for 27 minutes, including seven minutes beyond what was needed for observation before the breath test, and dismissed the charge. The case stated records his arrival at 12.55am, the start of the breath-test procedure at 1.07am and his departure at 1.27am. The High Court noted uncertainty about how the District Court reached its 27-minute finding and how the initial 12 minutes were spent.
Mr Justice Quirke said the prosecution does not have to produce evidence explaining every moment of detention in every case. But if detention is challenged as unreasonable, the prosecution must have an opportunity to respond and bears the onus of showing that its duration was reasonable. A dismissal on this ground would also require either a challenge on behalf of the accused or evidence raising sufficient concern for the District Court to begin a focused inquiry and allow the prosecution to meet that onus.
The case stated did not indicate that Mr O’Connor’s detention had been challenged or that such an inquiry had taken place. The High Court therefore answered “No” to both questions: the District Court was not correct to find the additional seven minutes unlawful, and was not correct to dismiss the charge. The judgment did not determine whether Mr O’Connor committed the alleged offence; it addressed the legal basis on which the charge had been dismissed.
